The Role of Water Flow Control Valve and Purchase Guide

The Water Flow Control Valve is a basic but important piece of equipment in a household water system. Whether it’s regulating the flow of water from the kitchen sink or optimizing a garden irrigation system, it can improve water efficiency and protect plumbing fixtures. In this article, Ventil DELCO will analyze in detail the types of common household plumbing valves, their functions and purchasing guidelines.

What is a Water Flow Control Valve?

A Water Flow Control Valve is a valve used to regulate, restrict or shut off the flow of water. It helps control water usage, stabilize water pressure and protect the plumbing system.

Types of common household plumbing valves

  • Gate Valves: Gate valves are one of the most common water valves for general residential plumbing. It allows the user to control a specific flow of water rather than simply switching between open and closed positions. Due to the controlled opening and closing mechanism, gate valves are ideal for homes that often experience water hammer problems.
  • Globe Valves: Provide precise flow regulation and are commonly used in piping systems that require fine control. For larger residential pipelines, globe valves are a good alternative to gate valves and are best suited to help minimize water hammer problems.
  • Ball Valve: Ball valves are also one of the common valves found in residential plumbing systems. Ball valves tend to be more reliable than gate valves and are less likely to leak or jam.With its fast opening and closing characteristics, it is suitable for water flow control scenarios that require full opening or closing.
  • Check Valves: Prevent backflow of water and protect equipment from reverse pressure.

Water Flow Control Valve for Domestic Scenarios

  • Kitchen: Installed under the sink, it is used to regulate the flow of water from the faucet, which facilitates cleaning and saves water.
  • Bathroom: Controls the flow of water from the showerhead, providing constant water pressure to enhance the bathing experience.
  • Garden irrigation: regulates water flow in the irrigation system to ensure even distribution of water.
  • HVAC systems: regulates water flow in heating or cooling systems to optimize energy use.

How to Choose the Right Water Flow Control Valve?

  • Clear application: Select the right type of valve (e.g. ball valve, globe valve) according to the application scenario.
  • Preferred material: corrosion-resistant brass or stainless steel valves are recommended for domestic water supply systems.
  • Suitable for piping: Ensure that the valve size matches the piping and meets the water pressure requirements at the same time.

Installation and Maintenance Recommendations

  • Installation location: Make sure the pipeline is clean before valve installation to avoid impurities affecting the sealing of the valve.
  • Regular maintenance: Check the valve for leaks and clean the spool of scale and impurities.
  • Troubleshooting: If the water flow is not smooth, try to adjust or replace the valve spool.
